FYP 1 Reflection of Progress 3 (Update)

Preliminary result

Figure 1 : Celullose-based capacitor structure

Table 1 : The electrical properties of the cellulose-based capacitor

-From the result, when the area increase, the capacitance value increase.

-So, the result satisfy the capacitance equation.
